I read on another forum that the HD brand of speaker wires oxidizes.
I bought this brand for my home theater.www.partsexpress.com
Sound King oxygen free 12 guage speaker wire.
100 feet for $29.00 on sale.
This is what I ordered for $29.00 but it doesn't appear to be on sale right now.http://www.partsexpress.com/pe/showd..._ID=2792&DID=7
or just do a search for Sound King by vendor.

Yes, that wire is the properly UL (I think that's the aproval rating) aproved for in wall wiring. This stuff comes in green and the 14ga comes in blue, which is the stuff I got. Great wire, with a high strand count.

Don't know what your cost limits are but you can use JPS Labs Super Blue Theater wire. It's UL rate for in wall use. JPS Labs I have this wire and their JPS Labs HDTV 75ohm wire running throughout my room.

Hey Kris:
I spoke to a guy at Home Depot in Edmonton, and he told me that their blue 14GA wire and the green 12GA was perfect for in wall use. He said it met all safety codes with no problem as long as it has that insulated jacket.
I am using the 12GA myself for my new house, and find it very affordable at $0.92 per Meter. That's three feet for you Americans.

I just tried to get on the Canadian Standards website:http://www.csa.ca/standards BUT the electrical page would not open!
I bet there is lots of info there for HT enthusiasts...IF the page would only work!!
